Mesnick, 33, will wed Malaney, 24 whom he met on the 13th season of the show, on ABC Monday, March 8 in a two-hour special. The episode will also feature Malaney going to dress fittings and planning the event. Former Bachelor and Bachelorette contestants will be on the guest list.

Back in October, when the couple announced their engagement, Malaney told UsMagazine.comthat she didn't know if they'd televise the nuptials.

"I don’t want to say no because you never know, but at this point, we don’t even know what we’re going to do about the wedding yet," she said at the time.
